Unable to write to ums lunfile (No such file or directory)

Hi every:
Recently and I don't know why my sdcard leave working as usual. I try to mount from recovery and get this message:
E:Unable to write to ums lunfile (No such file or directory)
Click to expand...
Click to collapse
So I don't know how to solve it. I try to read the SD in another phone and it reads OK without problem so SD isn't the problem, also I did format from Windows as FAT32 but still having the same problem, any help on this? It's possible it's a SW problem or it's HW problem? I'm freaking out

I have the same problem.
any solution?

I got the same problem, but I noticed my s off was now on too, I have the files to turn it back on from UNREVOKED through CWM or even flash back to stock image but I'm concerned this may brick my device as I'm not the most experienced user, any tips,knowledge or warnings before I try would be appreciated.

I'm having the same issue trying to reload my recovery mostly trying to get into recovery to instally my gummy rom. I cannot access my sd card via cwm 3.0.0.8 on my droid charge gummy charged 2.1 rom. Please help!

Ok, finally and after a deep, long, tedious Google search I found a solution, at least for me works and for now my memory and my phone are OK. Here is the steps:
1. If you have any recovery rename it to recovery.img and copy to the folder where you have fastboot.
2. Extract your SD and run this command:
Code:
fastboot.exe -c board_sapphire.disable_sdcard=0 boot recovery.img
3. Insert SD again
4. Run this command from adb shell
Code:
#mount /sdcard
Run as many times you need in order to get SD mounted.
This works for me so good lock for every of you that have the same problem as me in the past

Huawei u8800 MEGA PROBLEM!

Ok guys, so here is the deal
The phone was rooted and Oxygen ROM installed, but it has a major problem: The USB Mass Storage DOES NOT WORK! And the android market keeps closing(Force Close).
To install another ROM, you need to put files on your internal memory(the zip with the rom), but since the USB Mass Storage does not work, it seems "impossible".
You can't download files to the phone's internal memory, it asks for and SD Card.
Already tried putting the zip on external SD Card and then using ES File Explorer move it to Phone, but a message pops up saying that the file cannot be moved.
So the question is how to install another rom, or at least fix the USB Mass Storage problem. Is it possible to use external SD Card files on Clockwork Recovery like "install zip form SD Card"?
Also the internal memory and RAM capacity are not being shown correctly.
Thanks in advance!

dude it simple , if ur usb mode i not detected then take out the memory card and use a memory card reader to put other rom zip , if u dont have card reader then put the card in some other mobile fone use it to put the files . problem solved

It does read the external SD Card, but there is no option in ClockWork Recovery to install a zip from an external SD Card...

If you have oxygen installed, then you have the custom recovery image, which definately have an option to install zip from sdcard.

Tried through ROM manager, comes up with an error
SD Card marker not found...
Error verfying extendedcommand
And when you chose "Install Zip From SD Card", it goes to phone memory, which is kinda locked, cus you can still install the oxygen rom that's in there, but cannot place new files, already tried through ES Explorer(it fails).
Any suggestions?

I have the exact same problem, a solution I read somewhere is rebooting into recovery mode, and then go to "mounts and storage". There mount sdcard and usb storage.
Didn't work for me though, it gives "E:Unable to write to ums lunfile (no such file or directory)
edit: it's your lucky day, I just solved it after 3 hours of work ;D
what I did was:
- Go to recovery mode
- installed adb drivers (can't post URL because of not having 8 posts, i'll pm them if you want)
- put the cyanogenmod zip in the adb folder (for me "C:\Program Files (x86)\Android\android-sdk\platform-tools"
-opened up a command prompt and typed "adb push cgm.zip /sdcard
-then I installed from zip. phew!

Hey!
Yeah! That would be cool!
But where will i install those drivers? Tried copying cyanogenmod zip file from SD card to phone using ES Epxlorer and it failed... Tried creating new folder and it failed...
EDIT:
Oh... ADB drivers on PC...

[Q] TF101 doesn't recognize internal sdcard

I have CWMR 5,8 installed. First boot automatically loads into CWMR [this is, as far as I've read, a problem with the recovery and I can handle it if I can fix the internal sd card]. Rebooting and cold-booting helps me boot up my ROM (I've tried multiple ROMs, currently on CM9).
Everything works, except for my internal sdcard (weirdly thought I cannot access my external micro SD from CWMR). It seems as if its not mounted. I got ADB access to the device, /sdcard is there and all of the files are there. I can adb push and adb pull, so the internal storage seems to be working fine, it just doesn't mount it. Maybe the issue is permissions? ls -la sdcard outputs: lrwxrwxrwx root root 2012-10-26 20:43 sdcard -> /storage/sdcard0
Any ideas? I've tried installing different versions of CWM recoveries (adb push zip file and then using CWM to actually install it), they don't seem to stick.

Does /storage/sdcard0 exist on your device (AFAIK this is the new location defined by JB, but I don't know what CM9 does)?
If not, you may find your files in /data/media.

ok first thing, your external microsd card should be /Removable/MicroSD/. also what do you mean when you say youre pushing zip files then installing them but they dont seem to stick? how are you connecting via adb are you using ./adb shell to connect and move files? theres a certain way you have to push files to the device when youre in recovery.

Fixed it
Hello,
Not being able to mount the internal sdcard
The problem was I installed CM10 then somehow rolled back to CM9. The sdcard location moved between those 2 versions and the CM9 version wasn't able to mount it anymore. After installing CM10 everything worked apart from the boot loop.
TF101 booted into recovery every time
I fixed that by flashing: http://forum.xda-developers.com/showthread.php?t=1213723
and running the command to actually load in the new recovery from here: http://forum.xda-developers.com/showthread.php?t=1530337
In summary
My tf101 works thanks to all the info available on xda

[Q] Installing CM 10 - Cannot access SD card or Computer

Folks - Any help would be greatly appreciated.
I was trying to instal CM-10.1 on my U8800, copied the file downloaded from here on my SD card and used CWM to install. Forgot to make a backup (Noob mistake ).
The software didn't fully install and now the the problem is that while I can access both CWM Mod Recovery and the pink screen, I am unable to mound the external sd card (cannot write to ums lunfile) and neither are the drives showing up when I connect to the pc via USB in pink screen.
Very worried on how to install a rom as both internal and external sd cards are inaccessible by pc and phone respectively.

You can use adb push while cwm is running.

I'm not sure how to do that. I've just done a few google searches, not sure if I have the right results. Would you have any link/tutorial ?

If you haven't done so already, download and install the Android SDK from developer.google.com.
What you want from it is the debug driver and adb.
Then boot your device into CWM and connect it to computer, use the debug driver from the SDK.
Mount internal storage in CWM and check its mount location.
Open the folder where adb.exe is located on your computer and copy your ROM.zip to that folder.
Open a command prompt there and type "adb devices", your device should show up in the list.
Then type "adb push ROM.zip /mnt/sdcard/ROM.zip" to copy the file. (replace /mnt/sdcard if your internal storage is mounted elsewhere)
Good luck and be careful, I'm just trying to help but I'm not responsible if you do something without using some common sense.

Need Help Please

So I was about to flash a ROM and I had too many things on storage and cleaned and wiped everything. I then went on to use Format Data, hoping that it will only delete files and not the OS too. So now it deleted the OS and I'm stuck between bootloader or recovery mode and I can't seem to find a way to copy the zip file to my internal storage. Tried adb using cmd but it's not recognized and I'll have to dowload Google's SDK. This in turn will take about 2 hours and I'd really like to fix the problem ASAP. Anything I could do please?
Thanks and much appreciated.

You could always go to recovery, Mount your sd card and copy the file that way. Or setup fast boot and flash the stock image, or even just push the rom file through adb. You have a few options.

Adb-toolkit is in the folder but cmd is not recognizing it unfortunately. And through TWRP I have no option to mount USB... usb-otg doesn't work...

Anyone please? I have no idea what to do at this point and I'm pretty much phone-less...
